Hello,

Please review this small fix for JDK-8076311. Also, I need a sponsor for this fix, who can push it, because I'm not have a OpenJDK name. Fix for JDK-6521376 add explicit processing of MaxTenuringThreshold XX option. When bad value for MaxTenuringThreshold is passed(e.g. negative value for unsigned option "-XX:MaxTenuringThreshold=-1"), then function print warning and continue execution with default value(0). This behavior differs from Java 8. Java 8 process this situation in common way for unsigned options, i.e. print waring and reports a error. So, I fix Java 9 MaxTenuringThreshold option processing. Also, I add new test case to the test/gc/arguments/TestInitialTenuringThreshold.java to test this situation.
